Bang for your buck is what you get from ABS. From left to right is the master cylinder they come either chromed or polished, next is the electric vacuum pump, last but not least is the High Power accumulator. Like we mentioned earlier, if the worst should happen and you loose power or the system fails, the accumulator can hold enough pressure for 20 stops on the pedal. Now, what if you should use the pedal 21 times? You still have stopping power via the master cylinder.

Once the old booster is removed, you will see the bare firewall. At some point, this Nomad the firewall had been smoothed and filled. If your firewall has been altered, you will need a mounting plate from ABS. However, if your firewall is in stock shape, none is required.

Find a location to mount the electric booster. In our case the ABS technicians mounted it to the frame just underneath where the driver sits. The one thing we neglect to show you in this photo in the round sphere like power accumulator. It simply threads into the side of the electric booster.

Now that the electric booster has been mounted wiring it is the next step. The three wires that you see here are ground, hot wire and fuse box wire. It's simple enough right?

Don't forget the new vacuum line that runs from the electric booster to the back of the new master cylinder. Once all three are attached, hook the pedal up on the other side of the firewall. You're ready to fill the reservoir up and bleed the lines.

We love this final parting shot of the master cylinder. It looks right at home next to the rest of the polished and chromed items that may be lurking underneath your hood. Thanks to our ABS technicians, Ricardo Luna, and Guillermo Gomez, for their help with this '56.
